Red Eye

[not_so_new]

Hey all. I just sent this to Little Labs as well. They are a great company from what I know so I am sure they will get back to me soon but I figured I would ask around here to see if anyone has a quick answer for me.

My Red Eye whistles, any ideas why? '

It's not my amp, no microphonic tubes or anything. When I plug into the amp directly with my guitar using the same cables (except XLR of course), power and in the same room I don't have any whistling problems.

The only time it happens is when the Red Eye is plugged into my DA converters. I have the same problem with my Apogee DA-16X that I have with my UA-2192.

I assume there is some sort of impedance issue but that's what the Red Eye is for right?

Something seems odd here.

Thanks for the help if anyone has any input.
